You don't have to enter an email address. If you do, you will be sent a copy of your score.
You only need to choose 2 short answer questions. Use complete sentences! No maximum number of sentences, just make sure to completely answer the question.
When you submit, it will tell you that you have 4 unanswered questions. Those are the 4 short answers that you didn't choose. If you have more than 4 unanswered questions, go back and check your work.
The score you receive when you submit is only a total of the multiple choice and matching. The short answers will be graded and factored in later.
GOOD LUCK!!!
